In OpenSIPS you have 2 type of NAT modules:<br>
- for NAT detection, mangling SIP signaling and for doing the NAT
keepalive: you have here the NAT_traversal and nathelper, 2
similar modules as capabilities;<br>
- for media relay - modules that interact with an external media
relay for RTP; and here you have again 2 modules, the mediaproxy
and rtpproxy.<br>

<p>Hi Bogdan,</p>
<p><br>
</p>
<p>Thank you. Very well remembered!</p>
<p><br>
</p>
<p>Let me ask you conceptual question, please:</p>
<p><br>
</p>
<p>When should I use MediaProxy, not being necessary to use
NAT_TRAVERSAL and NATHELPER?</p>
<p><br>

<p>When should I use NAT_TRAVERSAL, no being necessary to use

<p>When should I use NATHELPER, not being necesary to use
MediaProxy and NAT_TRAVERSAL?</p>
<p><br>
</p>
<p>When should I use some kind of mix of these 3?</p>

<br>
User "make menuconfig" in order to auto-generate scripts -
the residential script has an options for NAT support.<br>

<p>Dear OpenSIPS-users,</p>
<p><br>
</p>
<p>I'm studying about NAT traversal with OpenSIPS, since
last week. I also have found the documentation about the
software MediaProxy (in
<a moz-do-not-send="true"
href="http://mediaproxy.ag-projects.com/">http://mediaproxy.ag-projects.com/</a>).</p>
<p><br>
</p>
<p>As long as I'm still getting 'kind of first steps'
knowledge base about NAT traversal, I'm not interested, at
least for a while, in MediaProxy software functionalities.</p>
<p>By the way, as a first contact with the NAT
traversal mechanism, I just would like to let the INVITE
from a caller reaches the callee, with caller behind a
NAT. For this purpose I have 2 questions:</p>
<p><br>
</p>
<p>a) Am I free of using a kind of mediaproxy
software, whether I want to build a prototype schema that
will just creates and sends an simple INVITE, from caller
behind a NAT, to a callee? That is, if I want just to run
a simple test of NAT traversal, I don't have to worry
about mediaproxies, have I?</p>
<p><br>
</p>
<p>b) How could be an example of a simplest script code for
that, considering that there is only one proxy for
all peers and all of it is registered in such proxy using
the same domain?</p>
<p><br>
</p>
<p>Any hint will be very helpful!!</p>
<p>Thanks a lot. <br>
</p>
<p><br>
